1 Great Plains Manufacturing, Inc. General Information Verti-Till ield pdate Installation Instructions for use with 5, 7 and 9-Shank Verti-Till ippers Applies to Models: VT5300A, VT5300 VT7225A, VT7225 VT7300A, VT7300 VT9225A, VT9225 General Information These instructions explain how to install the Verti-Till ield pdate. These kits bring recent engineering enhancements to several implement components. Each kit converts an entire implement. These instructions apply to:! When you see this symbol, the subsequent instructions and warnings are serious - follow without exception. Your life and the lives of others depend on it! Kit Kit escription A VT IE P SN JN A VT IE P SN JN07 If the implement is serial number 025 or lower, contact the factory regarding a third kit (596-83A) which is not described by these instructions. Implement serial numbers above 079 require none of these kits. Tools equired basic hand tools Verti-Till manuals: M Operator s P Parts a tractor with 2 hydraulic circuits and suitable hitch efore You Start igure Verti-Till ipper 2569 eview these instructions, and make sure you understand where and how the components install, and which existing parts are removed or re-used. Components in the two kits covered by the manual differ, based on the serial number of your implement. Sections specific to particular serial numbers indicate whether to apply or skip that section. Enough parts are included to update a 9-shank implement. There may be excess parts on 5- and 7-shank implements. Notations and Conventions eft and ight are facing in the direction of implement travel. An orientation rose in the line art illustrations shows the directions of eft, ight, ront, ack, p, own. to 40 callouts identify components in the currently referenced igure or igures. callouts reference new parts from the list on page 8. The descriptions match those on the cartons, bags or item tags, as well as your updated Parts Manual. 5 to 65 callouts reference affected existing parts from the table on page 20.

Inventory the contents per New Parts: Kits A and -85A on page Hitch the implement to a suitable tractor or hydraulic power source. Connect all hydraulic circuits. 3. ully lift the implement. 4. Place jack stands or other supports capable of supporting the implement weight under the main frame, or use a fork-lift at implement rear. IMPOTANT! o not rely on the transport lift cylinder locks to keep the implement raised. These cylinders are disconnected or removed during the upgrade. Note: The work can also be done with the frame supported by the rear shanks and front jack stand, but having it fully raised provides more access. 5. With the implement on the supports, set all hydraulic circuits to loat to relieve pressure in the lines and cylinders. eplace Pin etainers Notes On eplacing Pin etainer olts efer to igure 2 This kit upgrades Grade 5 pin retaining bolts to Grade 8. Grade 5 heads have markings with three lines 3. Grade 8 heads have markings with six lines 6. The implement may already have Grade 8 bolts in some locations, and require fewer bolts than are in the kit. If a Grade 8 is already in place, it does not need to be changed. igures for pin retainer bolt replacement are shown in exploded view for clarity. o not remove any components other than existing bolts and nuts. In particular do not remove pins (except where the pin itself is also being replaced). It may be necessary to drive a pin in the direction of the retaining bolt in order to free the bolt. New bolts are the same length or longer than existing bolts. 3 igure 2 Grade 5 vs. Grade M 08/06/2007
